Strongest Earthquake in 35 Years

Last night, a 4.7 magnitude Earthquake hit the central part of Arkansas. It was the strongest earthquake since 1976, when a 5.0 struck near Marked Tree (see above map). Many people across Region 8 felt the Earthquake, including my family. Here's a heliocorder from Gosnell, AR showing the Earthquake. I'm sure you can see where it is on this graph:

The Earthquake in 1976 and the Earthquake last night are not the same though. The Earthquake in 1976 was long the New Madrid Fault. The Earthquake last night... well, I'm not sure what that is about. If you click here, you can see how many Earthquakes we have had in northern Faulkner County recently and you can see every Arkansas earthquake in history. I have some theories on why there have been so many Earthquakes in Central AR, but there's not enough scientific evidence to even mention it on the blog. Something is different than in years past though....

Did you feel it? What are your thoughts? Feel free to comment!
